Question

Maglev, a vehicle that glides above a magnetic field without touching a track, make a 624-mile trip in 4 hours. What is the speed of the vehicle?

Answer 1

The speed of the vehicle is 156 miles per hour.

Step-by-step explanation:

Let suppose that the Maglev, that is, a vehicle who works on the principle of superconductive magnetic levitation, moves at constant speed. Hence, the speed of the vehicle (
`v`), in miles per hour, is defined by this kinematic model:

`v = (s)/(t)` (1)

Where:

`s` - Travelled distance, in miles.

`t` - Time, in hours.

If we know that
`s = 624\,mi` and
`t = 4\,h`, then the speed of the vehicle is:

`v = (624\,mi)/(4\,h)`

`v = 156\,(mi)/(h)`

The speed of the vehicle is 156 miles per hour.
